when the invention is used, the magnetic force end 31 is manually pulled to separate the second bolt 29 from the second U-shaped plate 30 and the first U-shaped plate 28, the reinforcing steel bar is placed inside the second U-shaped plate 30 (as shown in figure 1, the inside of the second U-shaped plate 30 can adapt to reinforcing steel bars with different thicknesses, the device is in a folded state at the beginning, wherein the second U-shaped plate 30 is positioned at the same side of the central vertical axis of the circular ring plate 10, namely the left end of the device, so that the reinforcing steel bar fixing is carried out without manual left-right back-and-forth penetrating, the reinforcing steel bar is longer, and the left-right penetrating may waste longer time), the second bolt 29 is penetrated inside the second U-shaped plate 30 and the first U-shaped plate 28, so that the first U-shaped plate 28 and the second U-shaped plate 30 are in a locked closed ring state (the magnetic force end 31 can be adsorbed on the side wall of the second U-shaped plate 30 to keep a locked state, and threaded reinforcing steel bars may appear because the reinforcing steel bars are not necessarily smooth, so that the two U-shaped plates 30 and 28 are respectively rotated to perform freedom degree conversion, so that the steel bars can slide to a certain extent relative to the steel bar rings, and the phenomenon that the steel bars are broken when the equipment runs due to hard contact between the steel bar rings and the steel bars is avoided, the equipment is slightly clamped, and the steel bars are seriously broken when the equipment runs is avoided, at this time, the power driving mechanism is driven, the power driving mechanism drives the first bevel gear 39 to rotate, the first bevel gear 39 rotates to drive the lead screw 38 to rotate, the lead screw 38 rotates to drive the directional displacement rod 35 to radially and upwards slide along the second long groove 37 formed in the side wall of the circular plate 10 (the lead screw 38 and the directional displacement rod 35 are in threaded connection and have self-locking and torque amplification, although the friction force is larger, stepless adjustment can be performed, so that the equipment runs more stably, the vibration is smaller, and the problem that the steel bar rings are prevented from being separated from the rubber plate 18 due to earthquake is solved), the directional displacement rod 35 moves upwards through the upwards moving long circular groove 36 to drive the first bolt 27 at the lowest end to move upwards, the first bolt 27 at the lowest end drives the second U-shaped plate 30 associated with the first bolt to move upwards, so that the steel bars in the second U-shaped plate 30 approach to the steel bar rings which are already fixed, the vertical upwards moving of the lower end of the first bolt 27 at the lowest end drives the lower end of the unfolding plate 26 to move upwards and rotate around the nearest second circular rod 25, meanwhile, the second circular rod 25 is pushed to move rightwards, so that the circular arc sliding blocks 24 slide along the inner wall of the circular groove 23, meanwhile, the clockwise rotation (viewed from the rear end of the device) of the unfolding plate 26 at the lowest end drives the unfolding plate 26 which is hinged with the first bolt 27 to rotate anticlockwise, so that the second circular arc sliding block 24 is pushed to slide rightwards and all the circular arc sliding blocks 24 synchronously and uniformly slide in the circular groove 23 in a diffusing way, in this process, all the exploding plates 26 also rotate to make the first pins 27 at the outer ends move towards the ring circular grooves 23 and revolve (the first pins 27 at the inner sides also move towards the ring circular grooves 23 and revolve), so as to ensure that the second U-shaped plates 30 also revolve and scatter around the axis of the ring plate 1 while following the moving edge, and approach towards the reinforcing steel bar rings (in this process, the reinforcing steel bars will sag due to their own gravity, and when passing through the horizontal central plane of the reinforcing steel bar rings, the reinforcing steel bars will be kept to slide close to the outer walls of the reinforcing steel bar rings to perform revolution and diffusion), thereby avoiding driving the reinforcing steel bars to rotate relative to the ground during diffusion (the reinforcing steel bars themselves have toughness and are not synchronous, thereby avoiding the problem that the reinforcing steel bars are subjected to torsional stress and the life is reduced), along with different sizes of the reinforcing steel bars, increasing or reducing the number of the circular arc sliders 24 to increase or decrease the number of the reinforcing steel bars (when the reinforcing steel bars are larger, the second U-shaped plate 30 is not spread to form a uniform sealing circle and then contacts with the reinforcement ring, so that a relatively closed reinforcement circle is formed due to the lack of reinforcement), and the number of the reinforcement and the size of the reinforcement ring are related, so that the strength of the reinforcement cage is ensured;
the invention drives the screw rod 38 to rotate through the power driving mechanism so as to enable the directional displacement rod 35 to slide and move up in the second long groove 37, thereby enabling the lower end of the expansion plate 26 at the lowest end to move up, enabling the expansion plate 26 to rotate, further driving the second round rod 25 to enable the arc sliding blocks 24 to slide along the circular ring groove 23, then enabling the adjacent expansion plates 26 to hinge and rotate oppositely through the first bolt 27, further enabling all the arc sliding blocks 24 to slide and diffuse along the circular ring groove 23, indirectly enabling the second U-shaped plate 30 with the reinforcing steel bars to rotate and displace around the axis of the circular ring plate 10 to uniformly diffuse, and then simultaneously approaching the fixed reinforcing steel bar rings, thereby enabling the reinforcing steel bars to be uniformly diffused and distributed around the reinforcing steel bar rings at equal angles for uniform diffusion, further ensuring that the welding intervals between the reinforcing steel bars and the reinforcing steel bar rings are equal, on one hand, avoiding the phenomenon of uneven welding points of the reinforcing steel bars in the welding process, lead to the reinforcing bar ring to appear local heating inhomogeneous deformation that appears, secondly avoided reinforcing bar and reinforcing bar ring to distribute inhomogeneous, lead to the poor problem of steel reinforcement cage quality to appear.
